【 摘 要 】

Two new fully oxidized polyoxovanadate cluster-based solids (C4N2S2H14)2[H2V10O28]$cdot$4H2O, 1 and (C4N2S2H14)5[H4V15O42]2.10H2O, 2 are crystallized under self-assembly process in the presence of cysteamine. In both 1 and 2, cysteamines are oxidized forming disulphide linkages and occur as counter cations. The organic cations assemble around V10O28 cluster anions in 1 whereas they aggregate around V15O42 clusters in 2. pH appears to be the structure determinant in the occurrence of decavanadate cluster in 1 and pentadecavanadate in 2, with the same counter cation.
